Fastest copy way to copy huge file from NAS to the pc?
Hi, I would like to know what the fastest solution to copy huge number of files (total size >1.2 TB) from NAS to the PC where it's connected with same LAN. A reason why I'm asking this is that I'...
You don't need a copy utility for the ReadyNAS, you need one for the PC if it's to be the destination for the files. If it's to a USB drive, then you can connect it directly to the NAS and use a built-in backup job.
It sounds to me like you are using ReadyCloud for file access even when connected locally. I know the Netgear setup guide points you in that direction, but it's really not the best way to go. You want to use a direct SMB connection.
As for a copy utility on the PC, robocopy (a built-in command used via command prompt) is quite powerful.
Hi,
Thank you so much for your suggestion. I definetly will consider to use robocopy which I never heard before, and I just checked with the Window's command prompt, I saw that feature 'robocopy /?'.
I actually tried freefilesync util command to copy file from NAS to the pc, but it's really slow. It's much slower than I expected. Acording to the transfer speed that appl shows, I supprisingly knew that that using wifi cinnection is faster than wired gigbit ethernet connection. But their performance is only around 13Mb/s. It already spent +20 hours to copy 500G data, and still it's in the half.
Note that I'm uisng fast broadband service, and my pc is high end desktop I purchased only 2 years ago. But, their wired NIC card might have low spec, and very long ethernet cable may not support gigabit spec, but still it should cover at least 100Mbps.
Again, thank you for your suggestion, and I'll try it soon.
Thanks,
Fujimaru.

Are you saying that you are getting 13 Mb/s with gigabit?
WiFi won't be faster than wired gigabit. It might match gigabit, but it can't be faster (since the NAS has a gigabit connection). But normally WiFi will be slower.
Also, lots of small files will take longer than fewer large files.

FWIW, I use robocopy myself. It's not faster than FreeFileSync or drag and drop. The benefits of using a copy utility are
- some can verify, which is helpful if you have connection drops
- they can more quickly resume folder copying, w/o starting everything over
- they can incrementally update (only copying files that have changed on the source).
robocopy is a command line tool, but there are some GUIs out there for it.
Robocopy is quite powerful -- it can verify and copy only changed files using the right command switches. It can't resume a failed copy, but skipping all unchanged files almost does the same (usually takes a bit longer to verify the files didn't change). It's my tool of choice at work, though part of the reason is prohibition on loading any unapproved software, even if free/open source.
The disadvantage is that it's a command line tool, which can be daunting for some (but not us old geezers who used the likes of CP/M and Unix in the pre MS-DOS days).
robocopy /? has a lot of information, and you can Google a lot of help, too.

I agree, and I have batch files that use it on several PCs. Generally they are tied into Acronis TrueImage (running when the TrueImage backup completes).
Some of the options require some effort to figure out (especially if you use them in combination), but it is worth the effort.
There is another Microsoft option (richcopy), but it isn't included in the Windows install. Like robocopy it goes back a few years, but it is still available for download.

Be aware Windows does indicate transfer speed in Bytes (B), not bits (b) - the ~13MB/s would perfectly fit either an average WiFi or a Fast Ethernet link or around 100 Mb/s.

That is certainly true, and I agree that 13 MB/s is a typical WiFi speed (and about what you'd see with fast ethernet).
Fujimaru also says it took 20+ hours to copy 500 GB (I'm assuming GiB). 500 GiB would take 87 hours to copy at 13 megabit/s, but only about 11 hours at 13 megabytes/sec. So the math doesn't quite work out to 20+ hours, but 13 MB/s seems closer to the actual transfer rate.
Fujimaru: You should be able to see the ethernet link speed by looking at the device properties in Windows, or on the network page in the NAS web ui. A CAT 5E (or better) cable can carry gigabit ethernet up to 100 meters. The CAT rating is usually printed on the cables.
